BUCKBOARD-WAGON.

SPECIFICATION forming part of Letters Patent No. 333,053, dated December22, 1885.

' Application filed June 11, 1885. Serial No. 168,427. (No model.)

Our invention relates to an improved buckboard-wagon, and has for itsobject to adapt the Vehicle for short turning, and to provide increasedelasticity of the wagon body or frame.

In the ordinary buckboard-wagon the reach is dispensed with, and theaxles are connected by elastic parallel slats or strips of wood, forminga springing platform,on which the seat is mounted. The platform is butslightly elevated above the center of the wheels, and if made nearly aswide as the space between the wheels will prevent the wagon from beingturned in a short space. If the platform is made narrow, its elasticityis reduced, and the wooden slats sag under the load imposed and remaindeflected.

Our invention consists in the novel construction and arrangement of theslats forming the vehicle-body and in a novel auxiliary metal spring forstrengthening the same, as hereinafter more particularly described andclaimed.

In the accompanying drawings, Figure 1 is a side view of abackboard-wagon embodying our improvements. Fig. 2 is a plan view of theunder side of the body of the vehicle, and Figs. 3 and 4 showmodificationsof the slats forming the body or frame.

In the drawings, A designates the parallel wooden slats or strips whichform thevehicle body or frame. The slats are arranged in two sets orseries, and extend from the respective axles to about midway of thewagon. The rear slats are fastened at their rear ends to a transversebed-piece or bolster, which is mounted on the back axle, b, and theforward slats are secured at their forward ends to a transversebed-piece, which is mounted over and pivoted in the usual manner to thefront axle, c. The slats curve upward from the axles, as shown, and arefastened at their opposite ends to parallel cross-bars d, which areconnected by longitudinal bars e. The wagon-seat h is mounted upon thecross-bars d, and further strengthens the connection between the slats.Thus curved and connected the slats form a 'strong"'and]graceful elasticframe, which is arched midway of its length, and has the wagon-seatsurmounted directly over the arch or point of greatest elasticity.

Arranged under the vehicle-body is an auxiliary spring, L, which isshaped to conform to the arch in the frame. The spring is secured at itscenter to the middle stay, a, and is bent around under the slats A,following their curvature. The ends of the spring are fastened totransverse bars M, which slats.

Constructed as abovedescribed and shown this form of buckboard-wagoncanbe turned in avery short space, as the forward wheels swing under thearch in the frame when the axle oscillates on its bolt or pivot. Thearched frame also has greater strength and elasticity than the ordinarybuckboard-wagon, and is more graceful in design.

When a two-seated wagon is desired, the rear ends, A, of the rear slatsmay project beyond the axle and curve upward like the forward ends, asshown in Fig. 3, forming a support for an additional seat.

If desired, the spring L may be dispensed with, and the arch properlystrengthened by iron braces, stays, or leather crossstraps; but thespring insures superior elasticity, and is therefore preferable.

It is evident that the upper ends of the slats may be fastened to asingle cross-bar or suitably secured to the bottom of the seat.

The body or frame of the wagon may also be made of a single series ofslats, A bent upward near the middle to form an arch, as shown in Fig.4.

We desire to secure by Letters Patent- '1. The combination of the frontand rear series of slats A with the auxiliary spring L, having its endsattached to the respective series of slats, substantially in the mannerand for the purpose specified.

2. In a double seated buckboard wagon having an arched frame, the rearseries of slats, A, bent upward at each end to form an elastic supportfor the respective seats, substantially in the manner set forth.
